DETAILED DESCRIPTION

As used herein, “mobile device,” “portable electronic device,” and “handheld electronic device” (i.e., handheld device) may refer to various types of portable processor-based devices, including but not limited to: notebook computers, digital assistants (e.g., personal digital assistants or ‘PDAs’), media players (e.g., MP3 players), mobile telephones, smart phones, mobile game players, digital cameras, portable recorders, tablet computers, portable e-ink readers, all-in-one portable computers, and/or portable television/s, etc.

As discussed above, conventional device covers provide a protective barrier between an external surface of the enclosed electronic device and the surrounding environment. In some instances, conventional device covers utilize protective films or plastic wrappers, for example, to provide protection to a display, or provide matting or anti-glare features. Conventional device covers may also provide plugs or covering for device inputs (e.g., touch-displays, actuatable buttons, or scroll wheels, etc.). However, such conventional device covers provide little beyond physical protection of the enclosed host device. For example, conventional covers do nothing to expand the mechanical utility and/or electrical functionality of the enclosed device.

Aspects of the subject technology address the above limitations by providing device covers and accessories that expand device functionality.

Cover/Attach Cover/Mechanical Cover:

In some aspects, the present disclosure relates to a cover (e.g., “a protective cover,” “a back cover,” “mechanical cover,” “a handheld electronic device cover,” “attach cover,” or “device cover”) configured to facilitate the attachment of various accessories. Attachable accessories (e.g., “accessory device,” “accessories,” “device accessories,” “attachment accessory,” or “accessory attachments”) may be used to expand the utility of the corresponding mobile device. The cover may include a surface (e.g., an accessory attachment area) on which the various device accessories may be coupled. The accessory attachment area may include an arrangement of connection points (e.g., catch receivers or receivers) that facilitate the mechanical coupling of the cover with various accessories. Although the number and configuration of accessories may vary, the cover may be configured to support the attachment of a single accessory, or the simultaneous attachment of two or more accessories.

It is understood that the cover may be constructed of various materials, or a combination of materials, including but not limited to: plastics, thermoplastics, thermoplastic polyurethane (TPU), polycarbonate, polyvinyl carbonate (PVC), and/or silicon, etc. The cover may be formed from a variety of materials including, for example, but not limited to soft, hard, rigid, flexible, compliant, etc. Some examples of material types include but are not limited to paper, plastic, metal, rubber, silicone, fabric, foams, leather, ceramics, films, and the like. The material generally depends on the desired needs of the outer covering. It should be appreciated that the outer covering is not limited to a single material and may include a combination of materials. The exact combination may depend on the needs of the outer covering. Examples of trade-offs include rigid/flexible, soft/hard, soft1/soft2, plastic/metal, silicon/plastic, etc. In one particular embodiment, the outer covering is formed from flexible and/or compliant materials such as rubber, silicone, fabrics (e.g., neoprene), and various films. Additionally, the cover may be constructed as a contiguous structure, or may function as a coupling of two or more separate but attachable portions. As discussed in further detail below, the cover may also include one or more layers, for example, that are fitted together to form one or more receivers, including a space recessed into the cover body, and that is configured to receive at least one projection associated with attaching an accessory.

In some aspects discussed herein, the cover is configured to enclose an associated handheld device (e.g., a smartphone) through the abutment of one or more edges of the cover with one or more edges of the enclosed device. However, it is understood that other coupling methods may be employed without departing from the scope of the subject technology. For example, a cover may be coupled to or around an electronic device through the use of friction coupling, i.e., whereby contact one or more cover surfaces create a frictional interference with one or more surfaces of the respective device. The contact may be a point, line or area contact so that the cover is coupled with the electronic device.

Accessory/Mechanical Accessories/Mechanical Device Accessories:

Aspects of the technology also relate to an accessory with a securement device for coupling an accessory to the cover. The securement device may be a plurality of projections. In some aspects, the device accessory is fastened to the securement device. In turn, coupling the accessory to the cover is accomplished by attaching the securement device with the cover, e.g., using one or more elongate projections as securement device configured for insertion into a respective receiver in the cover. In some aspects, mating of a projection into a respective receiver (i.e., a space of a receiver) may be controlled using a release button of the securement device.

As discussed in further detail below, various device accessories (e.g., a “kickstand,” “bike mount,” or “selfie-stick,” etc.), may be attached to the cover to expand device utility, for example, by securing the device to various surfaces, and/or by appending useful devices.

Cover/Electrical Cover/Electrical Attach Cover:

Other aspects of the technology relate to a cover that may be an electrical cover (e.g., “electrical cover,” “attachable electrical cover,”) configured to facilitate a transfer of power and/or data between an enclosed device and one or more accessories. The electrical cover may include a cover body configured for securement to an electronic device (e.g., an electronic accessory), as well as an electrical connector configured for coupling with a power port of the host electronic device.

Depending on implementation, the electrical connector may be a flexible wire or bus that may be plugged into a power/data port of the host device, such as a Universal Serial Bus (USB) port. Alternatively the electrical connector may include a rigid plug that is integrated into the cover body and configured for insertion into the power/data port, for example, upon securement of the cover to the host device.

As discussed in further detail below, the electrical attach cover is configured to facilitate power transfer between an electronic device enclosed by the electrical attach cover, and a device accessory, thus permitting a communicative coupling with a variety of electronic device accessories, including but not limited to: batteries, various data storage device/s, and/or wireless radios, etc.

Accessories/Electrical Accessories/Electrical Device Accessories:

Some aspects of the technology relate to accessories/electrical accessories/electrical device accessories configured for expanding the electronic and/or information processing capabilities of a host device enclosed by the cover. Depending on the desired implementation, the electrical accessories may be electrically and mechanically coupled with the cover, e.g., via electrical contacts disposed on one or more of the projections.

As discussed in further detail below, electrical device/accessories may include one or more power storage devices, memory devices, USB communication devices and/or wireless communication devices, such as Bluetooth® radios, WiFi, Wi-Fi direct devices, etc.

It will be appreciated that the disclosed systems and methods are novel, as are applications thereof of the components, systems, methods, and/or algorithms employed and included therein. It should be appreciated that embodiments of the presently described inventive body of work may be implemented in numerous ways, including as processes, apparatus, systems, devices, methods, computer readable media, computational algorithms, embedded or distributed software and/or as a combination thereof.

In some aspects, the handlebar attachment accessory 108 may also have a concave or contoured surface 112, for example, to facilitate a secure engagement with a tubular member, such as the handlebars 104.

The cover 106 (shown in FIG. 2 as the cover body 200), provides an accessory attachment area 114 providing coupling with one or more accessories. As may be appreciated in FIGS. 1A and 1B, the cover 106 may be coupled with various accessories, such as a mount for receiving the bicycle handlebar 104, thereby securing the mobile device 102 to the bicycle handlebar 104.

While the illustrated embodiment is drawn to the bicycle handlebar 104, it is within the scope of this disclosure for the cover 106 to be mounted to other objects or surfaces including, but not limited to: motor vehicles (e.g., a vehicle dash, vehicle windshield), clothing or accessories (e.g., a backpack, shoulder strap), surfboards, arm bands, carabineers, attachment of a stylus or pen, etc.

The cover 106 may be configured to cover a portion of one or more external surfaces of the mobile device 102 for ornamental and/or protective purposes. Additionally, the cover 106 can be configured to act as an electronic accessory to the mobile device 102, i.e., a supplementary system that improves the functional capabilities of the mobile device 102. In most cases, the cover 106 is a distinct element, which is not part of the originally designed mobile device 102. Instead, the cover 106 is an add-on or an accoutrement of the mobile device 102. The cover 106 may be configured to help protect the mobile device 102 (i.e., it may serve as an armor or shock protection that helps prevent structural and/or surface damage to the mobile device 102). Additionally or alternatively, the cover 106 may provide ornamentation to the mobile device 102 (i.e., it may help define the overall ornamental appearance of the electronic device). The cover 106 can also permit personalized ornamentation. The cover 106 may also provide tactility in order to improve the feel and grip to the mobile device 102.

The cover 106 can at least partially conforms to the outer shape of the mobile device 102. For example, by providing an internal shape/inner surface and/or being flexible enough to follow the contour of the mobile device 102. The external shape of the outer covering may be widely varied. It may be designed for ornamental, protection, and/or ergonomic reasons. Generally, however, it tends to follow the general shape of the mobile device 102.

The cover 106 may for example be laid, set, wrapped, spread upon, about or over a portion of the mobile device 102. The mobile device 102 may include a front cover and a back cover defining the front and back surfaces, respectively, of mobile device 102. The front cover may have a display for displaying image and the back side is a side that is facing different direction than the front side with the display. The front and back cover may toward opposite or different direction. The cover 106 may be configured to cover a surface of the mobile device 102 including a portion of a single side, multiple sides, and/or all sides of the mobile device 102. For example, the cover 106 may be a film/layer/cover that is applied to a single surface of the mobile device 102 (e.g., a portion or all of the back side).

The cover 106 may also be a flexible covering that includes a cavity for receiving the mobile device 102 or a flexible covering that wraps/stretches around some portion of the mobile device 102. The outer covering may be referred to (among others) as a case, shield, container, jacket, vest, skin, protector, and the like of the mobile device 102.

The cover 106 generally includes a body or member that couples to the mobile device 102. The body or member may also be removable or detachable from the mobile device 102. The body or member 202 may be carried by the mobile device 102, but is not part of the mobile device 102. The configuration of the body or member may be widely varied, but is typically configured to cover the outer surface(s) of the mobile device 102. The body or member 202 may be universal in its application (not specific to a particular device) or it may be dedicated to a particular device. In either case, the body or member can be configured to follow the outer contour or shape of the surfaces of the mobile device 102. In one example, the body or member forms a surface layer that attaches to the outer surface of the mobile device 102. In another example, the body or member forms an enclosure that includes surfaces (e.g., walls) that surround the outer surfaces of the mobile device 102.

The cover 106 may be adhered to or around the mobile device 102 using a variety of techniques including but not limited to: adhesive, friction, static, elasticity, suction, fasteners, snaps, connectors, and the like. In some examples, the cover 106 forms an enclosure that includes a void, cavity, opening, pocket or compartment for receiving a mobile device 102 therein (i.e., the mobile device 102 can be placed into the void). In another example, the cover 106 may be press fit onto the mobile device 102. In yet other examples, the cover 106 is a surface (e.g., platform, film) that is attached to a surface of the mobile device 102 (e.g., adhesive backed surface or surface with static electricity properties or a surface with suction cups). In yet other examples, the cover 106 is stretched around the mobile device 102 (e.g., the outer covering is flexible and conforms to the outer shape of the mobile device 102). In other examples, the cover 106 may trap or surround the mobile device 102 between multiple sections (i.e., lower and upper half). In accordance with one embodiment, the cover 106 may be formed from a soft, flexible and/or compliant material that can be wrapped around the various surfaces of the mobile device 102. For example, the material may allow the covering to stretch over the mobile device 102 (e.g., form fitting). By way of example, the cover 106 may be foamed from a stretchable material that includes a small opening that can be stretched to accommodate the larger mobile device 102 as it is inserted into the cover's 106 outer covering.

Once the mobile device 102 is inserted, the material conforms to the shape of the mobile device 102, which provides a tight fit around the surfaces of the mobile device 102. The cover 106 may, for example, surround multiple side surfaces if not all of the side surfaces of the mobile device 102. In one particular example, the material may be silicone. These types of coverings are sometimes referred to as “skins” as they create a new outer layer analogous to skin.

FIGS. 2 and 3 show a cover body 200 including a plurality of receivers 202 disposed on an accessory attachment area 204. The accessory attachment area 204 may be an outer back surface of the cover body 200. The receivers 202 may be arranged in a matrix (or lattice configuration) of rows and columns, wherein each of the individual receivers are separated in a regular spacing pattern. The receivers 202 may also be configured in a random distribution, or an isle or artwork. As discussed in further detail below, each receiver of a plurality receivers 202 may receive a projection (shown in FIGS. 5, 11, and 12), thereby coupling the cover body 200 with a device accessory. The cover body may comprise a base and at least one sidewall extending away from the base, the at least one sidewall being shaped to substantially conform to a handheld electronic device and the at least one sidewall comprising the attachment area with the plurality of receivers. The receivers may be arranged in 2 dimensional lattice such as bravais lattice, rhombic lattice, hexagonal lattice, parallelogrammic lattice or rectangular lattice. As for the shape of the receiver, the shape may be square, circular, rectangular, honey comb, or any kind of polygon.

It is appreciated that receivers 202 on the cover body 200 may be arranged in other patterns (e.g., not a matrix or lattice pattern). For example, the receivers 202 may be irregularly spaced, without departing from the scope of the subject technology.

FIG. 4 illustrates an example of a mounted device cover 400. In the implementation of FIG. 4, a cover body 200 is mounted to support 404 via an adjustable mount 402. The adjustable mount 402 may be coupled with the cover body 200 with one or more projections engaged with one or more receivers 202 disposed on an accessory attachment area 204.

The mounted device cover 400 may allow 360-degree movement of the cover body 200 relative to support 404 via the adjustable mount 402. The adjustable mount 402 allows a user to adjust the positioning of the cover body 200 to a preferred orientation.

FIG. 5 shows an exploded view of a cover 500 configured to couple with a kickstand accessory 504. The cover 500 includes a cover body 200 configurable with the kickstand accessory 504. The kickstand accessory 504 includes at least one projection 502 configured to be received in one or more receiver 202. The kickstand may have a first end and a second end. The plurality of projections 502 is placed on the first end for attaching the kickstand on the cover 200. The second end may be extended away from the cover 200 to form a supporting structure via the plurality of receivers and the plurality of projections for the handheld electronic device and the cover 200. The kickstand accessory 504 may be coupled at any desired orientation to support the cover 500 in a portrait position, a landscape position, or any position therebetween.

FIG. 6 shows an assembled view of a cover 500 coupled with the kickstand accessory 504. A projection 502 is received in one of receivers 202 on an accessory attachment area 204 of a cover body 200. The kickstand accessory 504 may be transitioned to extend away from the cover body 200 (as shown) and support the cover 500, or be transitioned substantially flush against the cover body 200 (as shown in FIG. 5). The kickstand accessory 504 may be substantially flush against the cover body 200 when not in use to reduce the profile of the cover 500. As used herein, ‘substantially flush’ may refer to a configuration whereby the kickstand accessory 504 is positioned adjacent to the accessory along the entirety of a contacting surface of the kickstand accessory 504.

FIG. 7 shows an isometric view of a handheld electronic device 700 having flip cover 702. The flip cover 702 has a cover portion and a coupling portion. The cover portion of the flip cover 702 as showed in the FIG. 7 with arrow showing 702 covers at least a portion of the front surface of an electronic device, such as a surface of the electronic device that includes a display. The coupling portion as showed in the FIG. 8 with the arrow showing 702 is coupled to the cover via the receivers 202 on the cover body 200. The flip cover 702 may be transparent or semitransparent so that information such as time, battery life, incoming call information, music information, camera interface may be projected through the flip cover 702. The flip cover 702 may have one or more apertures 704 therein to provide access to predetermined screen features, such as time, battery life, incoming call information, etc. In at least one embodiment, an apertures 704 formed in the flip cover 702 include a clear viewing surface such as glass, plastic, acrylic, or the like.

FIG. 8 shows a rear isometric view of a handheld electronic device 700 having a flip cover 702. In the illustration of FIG. 8 the flip cover 702 also covers a portion of a back surface of the electronic device, e.g., a surface that is opposite the front surface containing the display, as indicated above with respect to FIG. 7. The flip cover 702 may be coupled with the cover body 200 via the coupling portion and the receivers around an edge of the cover body 200.

FIG. 9 shows an interior view of a cover body 200. The cover body 200 has receivers 202 formed therein. The receivers 202 may be formed in a matrix of rows and columns (e.g., a lattice pattern) allowing a device/accessories to be coupled with the cover body 200 at one or more locations, positions, and/or orientations. While a lattice pattern is shown, any pattern or even a random distribution of receivers 202 may also be applied.

FIG. 10 shows a detailed view of one of the receivers 202. The receiver 1002 may have a space recessed into a cover body that is bounded, at least partially, by a recess wall 1004. The receiver 1002 includes an engagement surface 1006 configured for forming an abutting engagement with a projection associated with an accessory (e.g., kickstand accessory 504). While a circular receiver 1002 shape is shown in FIG. 10, the shape of the receiver 1002 may be square, rectangle, triangle, octagon, irregular, and so forth. The particular shape of the receiver 1002 may vary. The receiver may be a through hole, blind hole, interrupt holes, taper hole, taper holes with different taper angles at different section of the receiver. The arrangement of the receivers may be combination of the different type of holes.

FIG. 11 shows example an environment 1100 illustrating an engagement between a projection 1104 and a receiver 1110. As illustrated, the receiver 1110 is formed by a space recessed into the cover body that is bounded, at least partially, by a recess wall that includes an engagement surface 1108. In the illustrated example, the projection 1104 includes elongate mechanisms or member 1102 and protrusions 1106. Correspondingly, the receiver 1110 includes an engagement surface 1108 configured for abutting engagement with each protrusions 1106. The receiver may have a first end and a second end formed by the recess wall. The first end and second end may be shaped differently for better securement of the projection into the receiver. The aperture or opening of the first end may be smaller than the aperture or opening of the second end as showed in FIG. 11. When the projection 1104 is pressed through, coupled or engaged to the receiver 1110, the elongate mechanisms is compressed through the first end. As the projection is pressed to reach the second end which having a bigger aperture or larger diameter than the first end, the elongate mechanism may be recovered or decompressed to couple to the receiver 1110. The engagement surface 1108 and the recess wall may face a different direction. The protrusion 1106 is locked, coupled, or contacted with the engagement surface 1108 so that the protrusion is securely placed in the receiver. The contact may be a point, line or area contact so that the protrusion is securely coupled with the receiver.

As discussed above, the receivers (e.g., receiver 1110) may be disposed in a cover body in various locations or arrangements. In some aspects, the receiver is configured such that an inserted projection (e.g., projection 1104) extends away from a back-side of the cover body, e.g., wherein the back-side is opposite an interior cover surface of the cover. As further illustrated in the example environment 1100, the engagement surface (e.g., engagement surface 1108) may be configured to provide a surface that faces in a direction different from a surface defining the recess wall. By way of example, the engagement surface 1108 may face or substantially face toward a direction of an enclosed electronic device (not illustrated in FIG. 11).

FIG. 12A shows a detailed view of a plurality of projections received within a plurality of receivers (receiver 1204, receiver 1206, receiver 1208, and receiver 1210). The cover body section 1200 may accommodate various receivers engaged with a projection. As may be appreciated in the cross section of the receiver 1210 receiving the projection 1104, the engagement surface 1108 is abutting engaged with the protrusion 1106. The plurality of projections on the accessory may be arranged differently in consideration of accessory securement. As an example of the arrangement of the plurality of projections, the projections in the receivers 1210 and 1204 have the protrusions to securely coupled to the receivers, whereas the projection in receiver 1206 lack the protrusion to lock on the receiver 1206. The additional projection without the protrusion in the receiver 1206 may be used for security of a lateral movement or an angular movement with other projection. As for the projection with protrusion as in the receivers 1204 and 1210 may be used for limiting the lateral, angular, axial, or perpendicular movement. The number of the projection with protrusion may be configured to fit the ease of the attachment or detachment. As the number of the projections with protrusions increases, it is expected that the accessary is more secure on the cover. The placement of the projections may be a consideration, too. As shown in FIG. 12A, the receiver 1208 does not have a corresponding projection from the accessory to be inserted into. The projection may be placed on the accessory to accommodate the weight distribution of the accessory or the security requirement.

In some aspects, the number of the projections on the accessory may be less than the number of receivers on the cover. In other words, the number of receivers is more than the number of projections so that the accessory may be moved from a different location on the cover or having a second accessory attached to the cover at the same time. The accessory may attach to a different location or an orientation on the cover by using the same projection on the accessory to different receivers on the cover. For example, as shown in FIG. 12B the accessory may be moved from a first position to a second position by attaching a first set of receivers 1210 at the first position and attaching a second set of receivers 1211 at the second position. The first set of receivers 1210 is different from the second set of receivers 1211 by at least one receiver 1212. As the accessory moves further away from an original position, the first set of receivers used for attaching the cover and accessory has more different receivers used. There may be a second accessory attached to the cover. The first accessory may attach to a first side of the cover and the second accessory may attach to a second side of the cover using a different set of receivers.

FIGS. 13-15 show various engagement arrangements for a matrix of receivers. The matrix of receivers 1300 may be secured to a cover with a projection 1302 at four corners. As may be appreciated in FIG. 14, an additional center projection 1402 may be employed in addition to the projection 1302 at each of the four corners. As may be appreciated in FIG. 15, the remaining receivers of matrix of the receivers 1300 may be secured with the additional projections 1502. The shown arrangements are merely illustrative, and it is within the scope of the disclosure to implement any arrangement of the projections within matrix of the receivers 1300.

FIGS. 16-20 show various projection embodiments. As may be appreciated in FIG. 16, a projection 1600 is substantially circular and has a protrusion 1602 extending around the circumference of the projection 1600. As used herein, “substantially circular” may mean that the projection 1600 may have a circular or semi-circular shape, such as an oval or oblong shape or any other shape. The shape of the projections may correspond to the shape of the receivers on the cover. The shape of the protrusion 1602 may be different from the shape of the projection. The shape of the protrusion 1602 may correspond to the shape of the engagement surface mentioned above. As showed in FIG. 16, the shape of the projection 1600 is the same circular shape as that of the protrusion 1602. It will be apparent to those of skill in the art that other projection geometries may be implemented, without departing from the scope of the technology. By way of example, any of the projections implemented herein (e.g., projection 1600) may include symmetrical shapes (e.g., a square or rectangular shape), as well as non-symmetrical shapes.

As may be appreciated in FIG. 17, a projection 1700 may have an aperture 1702 formed in the center. As may be appreciated in FIG. 18, a projection 1800 may have two substantially equal portions 1804 each having a protrusion 1806 extending from the circumference and the center aperture 1802. The center aperture 1802 may allow displacement of substantially equal portions 1804 during securing and releasing of the projection with a receiver. As may be appreciated in FIG. 19, a projection 1900 may have two substantially semicircular portions 1902 and only one of two portions has a protrusion 1904 extending therefrom. As may be appreciated in FIG. 20, a projection 2000 may have three substantially equal portions 2004 each having a protrusion 2002 extending therefrom.

FIG. 21 shows an example engagement 2100 of a projection 2102 disposed within a receiver 2104. The example engagement 2100 includes the projection 2102 engaged in the receiver 2104. A protrusion 2106 of the projection 2102 may engage the engagement surface 2108 of the receiver 2104. The projection 2102 may be engaged with a receiver with a different opening at a different end or engaged with a through hole receiver. The projection 2102 is compressed through the receiver 2104 and decompresses at the end of the receiver and engaged on the surface of the cover via an engagement surface 2108. The projection described above and below may be engaged to a different kind of receiver to form an engagement of the cover and the accessory.

FIG. 22 shows an example engagement 2200 of a projection 2202 disposed within a receiver 2104. The projection 2202 has an aperture 2204 formed substantially in the center. The aperture 2204 may provide flexibility and deflection of the projection 2202 during securing and releasing by allowing a protrusion 2106 to deflect inward toward aperture 2204.

FIG. 23 shows an example engagement 2300 of a projection 2302 engaged with two receivers 2308. The projection 2302 includes protrusions 2304 engaged in respective receivers 2308 (e.g., two adjacent receivers) of an engagement surface or the surface of the cover 2306. Another example of a projection may be having the projection with a protrusion along one side as one of the projection 2302 described in the FIG. 23. The projection may engage to only one side of the receiver and a second projection of the same shape with a different protrusion extends toward a different direction may be placed at a distance for engaging another receiver.

FIG. 24 shows an example embodiment of a projection 2402 engaged with a receiver 2104. The example engagement 2400 includes the projection 2402 engaged in a space of the receiver 2104. The projection 2402 disposed in the receiver 2104 shown in FIG. 24 may be seen in FIG. 19 in uncoupled state.

FIG. 25 to FIG. 28 shows a projection with various centers that makes out of a different material or a combination of materials. The center or core may be composed of different materials to account for the rigidity of the projection and ease of the projection to engage with a receiver. FIG. 25 shows a projection 2500 having rigid material 2504 with a substantially hollow center portion 2502. As the projection 2500 presses or engages to a receiver, the projection is compressed toward the center hollow portion 2502. The projection may be decompressed to engage to the receiver in a secure manner.

FIG. 26 shows a projection 2600 having elastically deformable material 2602. FIG. 27 shows projection 2700 formed from elastically deformable material 2602 disposed around rigid material core 2702. As the projection 2700 presses or engages to a receiver, the projection is compressed toward the rigid material core 2702. The projection may be decompressed to engage to the receiver in a secure manner. FIG. 28 shows projection 2800 formed from elastically deformable material 2602 with rigid material core 2702 having substantially hollow center 2802.

FIGS. 29 and 30 show a secure pin arrangement 2900. The secure pin arrangement 2900 includes a projection 2906 with a substantially hollow center 2904 adapted to receive a secure pin 2902. The secure pin 2902 may prevent inward deflection of protrusions 2910, thereby preventing removal of the projection 2906 from the receiver 2908.

FIG. 31 shows a catch arrangement 3100 including a projection 3102 having an engagement surface 3104 formed to engage with and a locking structure 3108 formed within a receiver 3106. The locking structure may be a ball bearing installed in the receiver or latch structure that may be coupled with the engagement surface 3104. The engagement surface 3104 may be a concave surface on the projection 3102. The ball bearing structure may be locked or coupled with the concave surface to secure the projection to the receiver. The engagement surface 3104 may be a locking structure such as a ball bearing or latch and the locking structure may be a concave surface. The receiver and the projection may be coupled to each other vice versa.

FIG. 32 shows a releasable projection 3200 including an accessory 3202 configured for alignment with a cover body 3204. The accessory 3202 may have a release mechanism 3206 configured for releasable engagement between the accessory 3202 and the cover body 3204.

FIGS. 33-35 show actuation of a releasable projection 3200. The releasable projection 3200 includes a projections 3302 of the accessory 3202 configured for engagement with a receivers 3304 of the cover body 3204. The projections 3302 may be transitioned within the receivers 3304 by actuation of a release mechanism 3206. Compression of the release mechanism 3206 transitions the projections 3302 within the receivers 3304 from a secured position to an unsecured position (FIG. 34), thereby disengaging the protrusions 3306 from the cover body 3204.

The release mechanism 3206 may include a spring bias 3308 to bias a release mechanism 3206 to the secured position. In the unsecured position (FIG. 34), the accessory 3202 may be decoupled from the cover body 3204 (FIG. 35). While the biasing element is shown as a spring, it is within the scope of this disclosure to implement other biasing elements including, but not limited to, elastically deformable materials such as rubber.

FIGS. 36-39 show a slidable engagement 3600. The slidable engagement 3600 for use with a cover 3606 includes a first layer 3604 and a second layer 3602. The second layer 3602 includes apertures 3608 formed corresponding to the receivers 3610 of the first layer 3604. The second layer 3602 is slidable relative to the first layer 3604 providing alignment of the apertures 3608 with the corresponding receivers 3610. Transitioning the second layer 3602 to a receiving position (FIG. 37) allows receiving and engagement of one or more projection 3714 of the accessory 3712 with the receivers 3610.

After engagement, the second layer 3602 is biased toward partial alignment with the apertures 3608 and the receivers 3610 (FIGS. 38 and 39), thereby securing the accessory 3712 with the first layer 3604.

FIG. 40 shows a sliding arrangement 4000 having a first layer 4002 and two or more second layers 4004. The second layer 4004 may have apertures 4006 corresponding to a row or column within matrix of receivers 4008. The apertures 4006 may align with any configuration or pattern of the receivers beyond a row or column. Each second layer 4004 may be transitioned independent of the other second layer allowing one accessory to be coupled/decoupled from the cover 4010 without interrupting the coupling of other accessories in adjacent rows or columns of the cover 4010. The second layer 4004 may be operating by corresponding push buttons 4012 sliding the second layer 4004 relative to the first layer 4002.

FIGS. 41A and 41B show a lock arrangement 4100 of an accessory 4102 including a lock mechanism 4104. The lock mechanism 4104 may be rotatable between an unlocked (FIG. 41A) and a locked position (FIG. 41B). The unlocked position may allow compression of the lock mechanism 4104, thereby allowing the accessory 4102 to decouple from the cover body 4106. The locked position may prevent compression of the lock mechanism 4104, thereby preventing coupling or decoupling of the accessory 4102 from the cover body 4106.

FIGS. 42-45 show rotatable an engagement mechanism 4200 configured to engage an accessory 4202 with a cover body 4206. The rotatable engagement mechanism 4200 includes a rotatable lock mechanism 4204 transitionable between a secured position and a released position. As may be appreciated in FIG. 43, the rotatable engagement mechanism 4200 may have one or more apertures 4304 formed in the cover body 4206 and aligned with one or more receiver 4306. The receiver 4306 is configured to receive a protrusion 4302 of a projection 4308 in the secured position (FIG. 43). As may be appreciated in FIG. 44, the rotatable engagement mechanism 4200 may be transitioned to the unsecured position, thereby rotating the protrusion 4302 (shown in FIG. 43) away from the receiver 4306 and into the accessory 4202 (FIG. 45).

FIGS. 46 and 47 show a projection 4600 for engaging a receiver 4602 including a protrusion 4604 and a depressible button 4606. The protrusion 4604 is secured within the receiver 4602 unless the depressible button 4606 is compressed. As may be appreciated in FIG. 47, a lock pin 4702 may be disposed within the depressible button 4606 to prevent compression of the depressible button 4606. In at least one embodiment, the lock pin 4702 has a non-standard shape (e.g., a pentalobe) to prevent removal except by a user.

FIGS. 48-50 show an arrangement 4800 including a cover 4802 formed to engage each of receivers 4810 along a perimeter 4806 of a cover body 4804. The cover 4802 may have a plurality of protrusions 4808 disposed along edge and configured to be received in a plurality of receivers 4810 disposed along perimeter 4806 of the cover body 4804.
